GRAiN-OAR DOOR.

SPECIFICATION forming part of Letters Patent No. 569,923, dated October20, 1896.

Application filed November l, 1895. Serial No. 567,643. A(Nominated.)

To all whom, t may concern:

Be it known that I, WILLIAM J. JOHNSTON, a citizen of the United States,residing at Port Huron, in the county of St. Clair and State ofMichigan, have invented certain new and useful Improvements in Grain-OarDoors; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of refer ence markedthereon, which form a part of this specification.

his invention relates to car-door fixtures; and it consists in a systemof parts'and features made and arranged substantially as set forthhereinafter, and as shown in the accompanying drawings, in which- Figurel shows a View as from the inside of the car. Fig. 2 shows the doorraised, taken from a point at right angles to Fig. 1. Fig. 3 shows aview as from the outside of car. Fig. 4 shows a horizontal sectionseenfrom above. Fig. 5 shows a detail View.

The inside face of the car-door frame or stanchion on each side of thedoor is faced with metal plates. These metal facings are divided intotwo parts Aand A', with groove or slotway B between the parts andwidening behind the facings in space C, so as to allow hooks or ears Dand D', which hold the-door E in place, to move freely up and down inOpening and closing the door. Of these plate A extends a space beyondthe end of plate A', as shown, A being so fastened to frame as to beslightly movable and allow va-- riation in width of slot B.

The door is formed of two parts hinged together securely, the upper partF folding down and inward on the lower part E, or the upper part F maybe omitted. The lower part E has an gle-plates H upon the ends, with oneface or edge bent around the end and projecting beyond, so as to enterthe slotway B. At the top of this face is the hook or ear D, bentoutward, and near thebottom is the hook or ear D, bent inward, thepurpose of these ears being to catch back of the plates A and f and holdthe doors securely in place and, with the projecting edge of theangle-plate I-I running in the slot B, guide the door up and down. Thispart E has metal plate orangle-plate R at bottom edge to protect thebottom of the door, and also han: dles S on outside of door to assist inraising it.

The angle-plates II have near the top,` middle, and bottom three, ormore or less,lugs projecting through the door and parallel with theextending edge of I-I, forming a bearing 6o with the projecting edge forshaft ot' rollers K, which enable the door to be easily raised when loadis pressing against it from the inside. These rollers and the hooks orears may be, if desired, on separate parts and the y angle-plates partlyor wholly omitted.

The part E has staples G or arms at its ends on the upper corners, asshown. The door-frame has dependent hooks L at the top over the plate Ato catch and hold staples 7o G and prevent part E from getting out vofframe and to hold part E when swung out and hung up, as shown in Fig. 2.PartE has sliding bolts M on its outer face, arranged in bearings tofasten or lock the door,7 5 in place.

There are dependent hooks N from the car-roof to hold up the lower edgeof the door when it is open and swung up on hooks L and staples G.

At the point in slot B where the hook or ear D reaches when the door ishung on hooks L there is a notch or opening O in plate A through whichthe hook D can pass.

At the bottom of the door-frames there is a notch or widening of slot B,so as to facilitate the cleaning of grain or other matter from the slot.

When the door is to be opened, it is raised up and the top part F foldedback and in on 9o part E. Then part E is pushed up until hooks D escapefrom the slotway above plate A, when it is pushed inward at the top, soas to bring the staples G into hooks L. Then the lower edge of part E isdrawn out, the hooks D passing through notch O and hung on hook N fromthe roof. The door is shut by reversing this operation.

Various modifications may be made.

l. In a grain-car a shutter having a single metal plate on its end bentso as to cover the inner face of the ends of the shutter-timbers andbind them together, and to project into IOO a slotway in the door-jamb,and bent to one side within such slot to hold the shutter to the jam'b,all substantially as set forth.

In a grain-car, the combination with the jambs, metallic slotted guideson their inner faces, having nea-r the middle and at the top, cut-awayportions, of doors having a iiange at the edge entering said slot, andhooks on this flange within the slot, bails on the door, and hooks atthe top with which said bails are adapted to engage7 the flange -hooks,when the door is suspended, being opposite the cut-away portions.

f3. 1n a grain-car, the combination with the jalnbs, metallic slottedguides on their inner faces, a door having outwardly-projecting flangeson its edges, with means for preventing detachment except at its upperpoint, a hinged section at the top of the door, corresponding flanges onthis section adapted to enter the slotted guides, and bolts on the dooradapted to enter apertures in the j ambs.

l. In a grain-car the combination of ashutter-section having ears at thetop and bottom bent to the opposite sides, with door-jambs having meta-lguards with a slotway between arranged to engage with such ears to thejamb which is Within and hold the shutter in place while free to run upand doi'rn and having a space cut out on one side of such slotway at apoint arranged so the ear at the bottom can be drawn out inward from theslot to open the door, While the ear at the top of the shutterprojecting to the opposite side will pass such point without liabilityto escape from the slot, substantially as set forth.

5. The combination with the door-jambs, a vertical slotted guidetherein, ahooked fian ge on the end of the door engaging the slot, andfriction-rollers for the door on that portion of hidden or protected bythe liange, for the purpose speciied.

6. The combination with the doorjambs having guideways of a door, aroller-bearing, and a guard for said roller carried by the doors to keepthem free from the grain at all points of movement.

In testimony Whereoil I alix my si gnature in presence of two Witnesses.
